What is AgentScope?

AgentScope is a production-ready, easy-to-use agent framework with essential abstractions that work with rising model capability and built-in support for finetuning.

We design for increasingly agentic LLMs. Our approach leverages the models' reasoning and tool use abilities rather than constraining them with strict prompts and opinionated orchestrations.

Why use AgentScope?

• Simple: start building your agents in 5 minutes with built-in ReAct agent, tools, skills, human-in-the-loop steering, memory, planning, realtime voice, evaluation and model finetuning
• Extensible: large number of ecosystem integrations for tools, memory and observability; built-in support for MCP and A2A; message hub for flexible multi-agent orchestration and workflows
• Production-ready: deploy and serve your agents locally, as serverless in the cloud, or on your K8s cluster with built-in OTel support

Quickstart

Installation

AgentScope requires Python 3.10 or higher.

From PyPI

pip install agentscope

Or with uv:

uv pip install agentscope

From source

# Pull the source code from GitHub
git clone -b main https://github.com/agentscope-ai/agentscope.git

# Install the package in editable mode
cd agentscope

pip install -e .
# or with uv:
# uv pip install -e .

Example

Hello AgentScope!

Start with a conversation between user and a ReAct agent 🤖 named "Friday"!

from agentscope.agent import ReActAgent, UserAgent
from agentscope.model import DashScopeChatModel
from agentscope.formatter import DashScopeChatFormatter
from agentscope.memory import InMemoryMemory
from agentscope.tool import Toolkit, execute_python_code, execute_shell_command
import os, asyncio


async def main():
    toolkit = Toolkit()
    toolkit.register_tool_function(execute_python_code)
    toolkit.register_tool_function(execute_shell_command)

    agent = ReActAgent(
        name="Friday",
        sys_prompt="You're a helpful assistant named Friday.",
        model=DashScopeChatModel(
            model_name="qwen-max",
            api_key=os.environ["DASHSCOPE_API_KEY"],
            stream=True,
        ),
        memory=InMemoryMemory(),
        formatter=DashScopeChatFormatter(),
        toolkit=toolkit,
    )

    user = UserAgent(name="user")

    msg = None
    while True:
        msg = await agent(msg)
        msg = await user(msg)
        if msg.get_text_content() == "exit":
            break

asyncio.run(main())

Voice Agent

Create a voice-enabled ReAct agent that can understand and respond with speech, even playing a multi-agent werewolf game with voice interactions.

Realtime Voice Agent

Build a realtime voice agent with web interface that can interact with users via voice input and output.

Human-in-the-loop

Support realtime interruption in ReActAgent: conversation can be interrupted via cancellation in realtime and resumed seamlessly via robust memory preservation.

Flexible MCP Usage

Use individual MCP tools as local callable functions to compose toolkits or wrap into a more complex tool.

from agentscope.mcp import HttpStatelessClient
from agentscope.tool import Toolkit
import os

async def fine_grained_mcp_control():
    # Initialize the MCP client
    client = HttpStatelessClient(
        name="gaode_mcp",
        transport="streamable_http",
        url=f"https://mcp.amap.com/mcp?key={os.environ['GAODE_API_KEY']}",
    )

    # Obtain the MCP tool as a **local callable function**, and use it anywhere
    func = await client.get_callable_function(func_name="maps_geo")

    # Option 1: Call directly
    await func(address="Tiananmen Square", city="Beijing")

    # Option 2: Pass to agent as a tool
    toolkit = Toolkit()
    toolkit.register_tool_function(func)
    # ...

    # Option 3: Wrap into a more complex tool
    # ...

Agentic RL

Train your agentic application seamlessly with Reinforcement Learning integration. We also prepare multiple sample projects covering various scenarios:

Example	Description	Model	Training Result
Math Agent	Tune a math-solving agent with multi-step reasoning.	Qwen3-0.6B	Accuracy: 75% → 85%
Frozen Lake	Train an agent to navigate the Frozen Lake environment.	Qwen2.5-3B-Instruct	Success rate: 15% → 86%
Learn to Ask	Tune agents using LLM-as-a-judge for automated feedback.	Qwen2.5-7B-Instruct	Accuracy: 47% → 92%
Email Search	Improve tool-use capabilities without labeled ground truth.	Qwen3-4B-Instruct-2507	Accuracy: 60%
Werewolf Game	Train agents for strategic multi-agent game interactions.	Qwen2.5-7B-Instruct	Werewolf win rate: 50% → 80%
Data Augment	Generate synthetic training data to enhance tuning results.	Qwen3-0.6B	AIME-24 accuracy: 20% → 60%

Multi-Agent Workflows

AgentScope provides MsgHub and pipelines to streamline multi-agent conversations, offering efficient message routing and seamless information sharing

from agentscope.pipeline import MsgHub, sequential_pipeline
from agentscope.message import Msg
import asyncio

async def multi_agent_conversation():
    # Create agents
    agent1 = ...
    agent2 = ...
    agent3 = ...
    agent4 = ...

    # Create a message hub to manage multi-agent conversation
    async with MsgHub(
        participants=[agent1, agent2, agent3],
        announcement=Msg("Host", "Introduce yourselves.", "assistant")
    ) as hub:
        # Speak in a sequential manner
        await sequential_pipeline([agent1, agent2, agent3])
        # Dynamic manage the participants
        hub.add(agent4)
        hub.delete(agent3)
        await hub.broadcast(Msg("Host", "Goodbye!", "assistant"))

asyncio.run(multi_agent_conversation())
